MII / NAL Certification

The certification for imported goods

For foreign manufacturers, NAL certification is mandatory for affected telecom products before a product can be imported and marketed in China.

The first product categories for NAL approval were introduced in 2001, and there are now 28 categories from three different main groups:

  • Telecommunications Terminal Equipment
  • Radio communication equipment
  • Telecommunications equipment for inter-network connection.

There are now over 300 telecommunications products defined in the categories. These include communications or networking equipment with interfaces to public networks or wide area network (WAN) services. Common communications interfaces include T1/E1, ISDN BRI, ISDN PRI, ADSL, serial and analog PSTN.

If NAL approval is required for a product, this means that CCC certification is also required for the product. In addition, SRRC certification is a prerequisite for NAL approval.
